I think this has probably been debated to death on the interwebs...however I want to debate it here. Turbosocks CAI install thread sparked it in my head as I get closer to finally tossing an intake on.


Is there really real proof, and real data that shows that a CAI really does any better than an SRI? It just never made sense to me that it made that much a difference. And what if you just rout cool air from the gril to the SRI instead of having an extra 2 feet of pipe for your intake charge to run through to get from the bumper.

Are there hard facts on this? And I'm not saying hard facts like Injen's "testing" either, because all that is, is to sell the more expensive product. I'm talking independent testing.

I personally didnt notice any difference between the 2. I have also not seen any independent testing done. The only reason the CAI makes anymore power is because of the colder air. If you could manage to get the SRI the same temperature air without restricting it any further it would make the same power.

I will not be going in for another dyno to test it but I could do some logging and graph whatever differences from the data back to back under similar runs if you would like.

I believe the gains from the CAI will actually be quite negligible and well within an error of any dyno. What I am saying is, you could do three runs with an SRI and the results would be different enough that when you compared it to 3 dynos with a CAI, there would be overlap for sure.

The positive to having a CAI is that you are getting colder air all the time whether on or off the throttle.

Now to go into another tangent.. I would almost bet that a SRI with my FMIC kit would do better than the CAI as the air would be forced more into the filter than the CAI..

Hmmmmmm. Very interesting. And why would the air be forced more into the SRI with your FMIC?

 

[Turbosocks]

as the filter sits behind the stock intercooler, it is blocked from most of the flow in the stock setting. With the stock intercooler gone, all of that air is flowing freely right to the filter.

Ahhhhhhhhhh good call. didn't think about that.

along with water and other debris too... but thats just me...

 

[NoXiDe]

Exactly what I was thinking. Got to get the FMIC kit!

On the topic of intakes.....most people are using 2.75" I believe....anyone step up to 3" piping? If so does it yield better results than the 2.75"?

2.75" just seems so small as I am used to the 4" intake on my old trailblazer SS....

Not just you. I was thinking the same thing. Since Hyundai put pieces in the grill to direct air to the stock intercooler, once it is replaced by a different FMIC in a different position, what stops other undesirable material from passing through the grill to the SRI filter?
